Legend has it, that Flowey is still falling to this very day.

The fact Flowey just keeps falling indefinitely at the beginning is just so funny to me. Very in-line with Undertale's humor.

Hearing people discover Toriel = Tutorial feels a lot like people discovering Miles "Tails" Prower - Miles Prower - Miles Per Hour.

Hearing that so many people didn't know why Toriel was called that surprised me. For another fun name origin, it's explicitly stated in game that Asgore is famously bad at naming things. This is presumably why his son is named Asriel: he just smashed his and his wife's names together for their kid.

8 years and people still keep finding stuff in this game, that's pretty impressive.

<a href="#" class="seekto" data-time="180">3:00</a> flowey has gone where no flower has gone before

Despite everything Gaster is still hidden well

As someone who knows an unhealthy amount about this game, I am glad that there was so much I have never seen. By the way, Madjick underneath the hat layer is literally just Scripulous Fingore.

I like how the beta MTT hotel actually spells out MTT using the window door frame and carpet.

<a href="#" class="seekto" data-time="167">2:47</a> « Now, the Funniest thing you’ve ever seen, from very far away »

When this game first came out, I was obsessed with it, I spent so long trying to learn every little detail about it. Watching this video has taught me new things I didn't know about, it's actually very refreshing to see.

To this day, Flowey is, in fact, still falling indefinitely... Very fun and interesting video! I never thought this game could hide that many secrets

<a href="#" class="seekto" data-time="104">1:44</a> The mixture of dread and incredulity I felt upon seeing those eyes is indescribable.

As someone who uses GameMaker to game dev, this is so interesting to me and I want to speculate/talk about some parts of the video. (And sorry for all the parentheses.) <a href="#" class="seekto" data-time="156">2:36</a> - My theory for this is that Toby initially coded it so that Flowey would drop down instead of float off to the side, hence the gravity physics, but set it as an alarm (in GM, an Alarm is an event that runs code after a specified amount of time). However, whenever he changed the cutscene so that Flowey just floats horizontally off-screen, since the drop happens afterwards, he never removed it from the code. <a href="#" class="seekto" data-time="185">3:05</a> - I'm going to assume the SOUL isn't always in that specific Y position since it makes more sense that Toby would just code it in that when it's off-screen, it just sets its X position off-screen since that would be enough, then when he needs it back on screen, it just moves back to the correct X position. <a href="#" class="seekto" data-time="227">3:47</a> + <a href="#" class="seekto" data-time="507">8:27</a> - I think it's really interesting how Toriel and Alphys have this built into them. My theory is that Toby built it in so that when Frisk is facing and touching a character, their mouth moves, but I'm not sure about that one. <a href="#" class="seekto" data-time="240">4:00</a> - The switch still being present makes me think there's some code in the lasers that checks for the frame of the sprite to determine whether or not to show the lasers. If Toby had removed it from the room, that code would have broken,. So, instead of fixing the code (which would take a while), he just left the switch out of bounds as a quick fix. <a href="#" class="seekto" data-time="278">4:38</a> - This code is probably fine, but it hurts me. <a href="#" class="seekto" data-time="316">5:16</a> - The alternative to having default text is the game crashing, so that makes sense. Just a bit surprised Toby left it as a simple "* Error!" <a href="#" class="seekto" data-time="393">6:33</a> + <a href="#" class="seekto" data-time="422">7:02</a> - Since GameMaker isn't a 3D engine, to make sure characters can have proper layering, Toby would need to write in code to make sure characters can appear "in front" of other objects, most likely using depth = -y; ("Depth" is GameMaker's way of doing layering, with the lower the number, the more "in front" it is). This character in the Librarby and Greater Dog should probably have been above the table, but this code would have stopped that. Although Greater Dog was probably moved so far down under the table since he may have blocked too much of the the room behind him had he been higher. <a href="#" class="seekto" data-time="434">7:14</a> - When the snow-hat is created, it chooses a random frame of the snow-hat sprite. This happens in the Create event, which GameMaker runs when an object first spawns into a room. After the Create event has ended, the game begins running the Step event on the next frame (the Step event runs every frame after the Create event). This "Step" event is where code is that moves the snow-hat to Frisk's head instead of their torso, where whatever code initially spawned the snow-hat placed it. (When creating an instance of an object in the version of GameMaker Toby used, you have to specify the X and Y values alongside what object you're spawning. So, for this, the code was likely "instance_create(obj_human.x,obj_human.y,obj_snowhat)"). <a href="#" class="seekto" data-time="460">7:40</a> - Toby could have done this really smart or really dumb, and knowing Toby's abilities as a programmer when making Undertale, it wouldn't surprise me if he did it the dumb way (but I doubt it). GameMaker has a function called "draw_sprite_part" which, very literally, draws only part of the sprite on the screen. More and more of Doggo's sprite, as he moves up, would be drawn and then, by the time he's above the counter, his entire sprite, legs and all, would be seen. (For anyone confused what "draw" means, because I was before I began programming, it just means to show something on screen.) The dumb way is to have it be its own animation, with a different frame for each new line of pixels revealed as he goes up, which, while not by a lot, takes up more storage space. <a href="#" class="seekto" data-time="473">7:53</a> - Since GameMaker doesn't have built-in reflections, this is exactly what you think it is. There are two Frisks. The one you control, and the other one that matches your movements (albeit while inverting your up-and-down movements) that is just hidden behind the wall. <a href="#" class="seekto" data-time="488">8:08</a> - This makes sense from a coding stand-point. It's much faster to code Alphys to "go to the X-position of the door" than to go into the room and manually check to see where the door is and input a numerical X value. <a href="#" class="seekto" data-time="597">9:57</a> - The placeholder versions just include the tiles used in Snowdin's exterior tileset, which were likely Toby's way of blocking out the collision so that when he or Temmie made the final image of the room, it could just be slotted in without any tweaking. <a href="#" class="seekto" data-time="637">10:37</a> - Toby could have saved a bit more storage space making those waterfalls smaller. They're way too long and could very easily be chopped in half and still work, having the objects jump back to their original Y positions after a few milliseconds unlike the whole second they take. But that's just nitpicking. <a href="#" class="seekto" data-time="670">11:10</a> - The coloured backgrounds exist because GameMaker rooms have a background colour. Toby likely set it to random colours as they didn't matter when he would be putting the background images (in this case, the gradient) overtop of them. GameMaker has, as of 2017, done away with Backgrounds as an asset type, converting backgrounds to regular sprites, but they existed in the version Toby used to make Undertale. Backgrounds tile endlessly (hence why you've been seeing that the whole video whenever the camera zooms out). The reason why Gerson's shop doesn't have this happen, is because that is a Sprite, not a Background, so it doesn't repeat when zooming out. It's actually really interesting because GameMaker rooms have a set size, cutting off the tiling while you're editing the room, so Toby would never see all of these tiled backgrounds; the only way to see the background tiled this many times is by using Grossley's camera hack. <a href="#" class="seekto" data-time="693">11:33</a> - Something Shesez doesn't cover here is the dialogue box detaching from the text and talking sprite for Toriel. This is because all of these are separate elements that are placed on screen, but they're not programmed to move around the screen, since the camera doesn't move when text is on-screen. This is an EXTREMELY fantastic video, and thanks to anyone who read this comment for letting me geek out.

<a href="#" class="seekto" data-time="580">9:40</a> Sans looks so funny on that zoomout

PLEASE do a part 2! You barely touched on a lot of stuff that would have been really interesting, such as the endings. Specifically Pacifist, because Toriel also throws a fireball at him the same as Flowey. Would love to know what happens to him

<a href="#" class="seekto" data-time="570">9:30</a> I finally get why the game's called Undertale dude, you gotta literally look under the ground to see the world for what it is, Toby Fox you've done it again This was actually a pretty neat dive into the game! I liked seeing the remains of a scrapped concept at <a href="#" class="seekto" data-time="333">5:33</a>, cool stuff

<a href="#" class="seekto" data-time="626">10:26</a> So this implies that Sans builds a hot dog stand around the "shortcut" doors and that's how he appears everywhere so quickly. That or he already had sentry stations there and put in shortcuts so he wouldn't have to walk.

<a href="#" class="seekto" data-time="379">6:19</a> that character behind the counter is basically Berdly. Looks very similar, works in the library, and even the library in deltarune has the same layout for the most part.

<a href="#" class="seekto" data-time="207">3:27</a> I love that after all these years, I still occasionally get to hear someone have that realization. What if you delete the "bathroom" door entirely? What will Alphys do? Will the game just crash or soft lock?

One extra thing that I was wondering about is the bed in MTT. You can go under the bed and become the bed lump, so I was wondering what happens if you remove the image for the bed.

In the beta graphics underneath the outside of the hotel, the door also resembles the shape of a T. So from top to bottom you can read MTT on the front of the building, which is actually a really creative idea.

I like it when its revealed that there's actually a character sprite that you're talking to when they're hidden behind something, just shows that the age old trick of placing a sign (or something similar) behind something you want to have text is almost always the easiest option

<a href="#" class="seekto" data-time="507">8:27</a> Fun fact: using (parentheses) in dialogue is a way to indicate both inner thoughts) and whispering/muttering. My new headcanon is that Alphys is just saying this line while hoping you go away.

The Undertale Debug mode actually gives you access to most of this content since there's a command that removes all collisions in all rooms, as well as a teleport command that can also teleport you to some unused or placeholder rooms (although it's easier to teleport to a certain room by entering its number in Undertale's file0. You also have to use a Hex Editor to enable Debug mode and access to most of the unused and placeholder areas). Or you can use a mod like Shesez does in this video. The Debug mode doesn't have any zoom out commands or commands to remove/make sprites invisible.

<a href="#" class="seekto" data-time="207">3:27</a> It's okay, I didn't realize that Asriel is a combination of Asgore and Toriel's names until like 3 days ago.

<a href="#" class="seekto" data-time="536">8:56</a> sorry mat, there's no phase distorter

<a href="#" class="seekto" data-time="45">0:45</a> Petting Time 🐶!

It's actually really cool to see that so many scenes in this game still basically have their block-outs hidden underneath the final graphics, considering the flowers text triggers based on coordinates, I wonder if that was to make sure that scripting could be reused and it wouldn't look weird.

In REAL time you and I managed to have the same exact reaction to 2 Torial, which is the wildest thing I've experienced just watching a KZfaq video. Honestly, with all the great discoveries here it makes me wonder if a Deltarune episode would yield just as many cool notes and facts. Definitely blew past my expectations with this one!

it's quite refreshing to learn new things after knowing about every meticulous detail about UNDERTALE for YEARS upon YEARS! thank you!

Lots of cool finds! I never would have expected Madjick had eyes this whole time 👀

<a href="#" class="seekto" data-time="354">5:54</a> little did temmie know... the game would LITERALLY become one of the most beloved games in gaming

The laser switch on the side is because sometimes it’s easier to just trigger the switch through code, instead of rewrite all the code to disable the lasers.

It's awesome that Undertale has things hidden in it, One you wouldn't expect.

Even with the breaking of Camera and Getting Layers we still cannot find Gaster. He is to hidden fr

Fun fact, in french kill is "tuer". So kill toriel is actually "Tue toriel"

So monster kid in the bushes at <a href="#" class="seekto" data-time="450">7:30</a> makes me think of something. So there’s a room in the game files that’s full of grass like what monster kid hides in. In this room, there’s an unseen NPC that says something along the lines of “Who’s that behind you, the one with the smile?” Is there anything interesting behind that grass? This has been a big question amongst theorists of this game, and finding anything cool could finally shed some light on the situation

It amazes me that there are still things being discovered about this game 8 years later

Two Toriels... It's real! Now we just need two small pianos.

<a href="#" class="seekto" data-time="563">9:23</a> 😶 became 🙂

<a href="#" class="seekto" data-time="109">1:49</a> toby likes putting in funni secrets

<a href="#" class="seekto" data-time="279">4:39</a> I'm a programmer and. Oh my God that's SUCH an awful way to handle dialogue lmaooooooo

Never thought Undertale would even be possible but I'm so glad it is! Edit: It's great how we're still finding out new stuff about this game after all this time!

I hope we get an episode on Deltarune soon!

<a href="#" class="seekto" data-time="204">3:24</a> It is, I think Toby confirmed it, she is the tutorial lady, but it's more similar to the French translation of the word tutorial, as it is tutoriel

The music in Undertale still gets me to this day, I love it so much

This is great, your work is invaluable for design study

I am very surprised I have never heard of these things before in undertale, despite being a fan of it before and watching a lot of boundary-break type videos.

Great video as always Shesez! I also discovered the "two-Toriel" thing when I was sequence breaking the game. Something else I discovered is that when you enter the Waterfall hub area (the room that connects to Undyne and Napstablook's houses) Napstablook will turn around and greet the player then float off screen. However, if you spawn into that room, you can "talk" to Napstablook as the dialogue only gets activated if you're at the bottom entrance. The text is the same as when you "talk" to Mad Dummy before the fight begins. This is unusual as most character sprites that you can't talk to don't have collision or any dialogue if you do manage to reach them before they walk off screen.

Normally you CAN see more of Greater Dog's sprite in the game. Idk why he is lower for you. Does he pop up when talked to? I just remember him making a goofy face. But I know I've seen him higher where I can see the cards.

<a href="#" class="seekto" data-time="442">7:22</a> so this what he mean by sans frank you across space and time.

Being someone who makes games with gms2 (same engine as undertale) it’s really fun to see how the game actually handles things and how Toby did it, I’m not even gonna lie I learnt a couple things from this vid I didn’t know where possible with gms2 EDIT: the switch of screen at <a href="#" class="seekto" data-time="238">3:58</a> is probably there because of how Toby made the lazers, I suspect they where initially all supposed to be either on or off and had to have an active instance of the switch in the room, so in this room where I assume was an afterthought he had to add an offscreen switch. Additionally it may be tied to global variables associated with alphyus being able to turn them off and so as to save a couple steps just added an if for player hp to turn them off.

Two Toriels?! WHAT?! Hahaha I love this stuff so much 💓

interesting! I'm familiar with gamemaker and it's neat to see how he did some of these things. in particular the backgrounds that have a beta version behind them - this suggests that the original backgrounds were built with tiles and the final versions were stored as a single image placed over the top of the existing beta map

Nice to hear you back 😃

<a href="#" class="seekto" data-time="279">4:39</a> thank you for including that one

This channel never ceases to amaze me. I'm so glad this channel and everyone on it exists. Thank you for making a channel worth watching on KZfaq. Love everything you do and all the hard work put into it. Great series, great channel, great people, great content. Just love it :)

Okay, but the one that got me was Madjick having anime eyes lol.

<a href="#" class="seekto" data-time="210">3:30</a> Following the trend of her family: Tutorial Dreamer/Murderer. Important that she ditched the last name, as confirmed in her text messages

This is my absolute favorite game and it's so fun to learn new things about it even to this day

I used to use GameMaker a ton, so a Boundary Break for Undertale's gonna be crazy fascinating! I love what the battle sprites do, their little bounces and tweens are so dang cool to me. Madjick having eyes is important lore.

<a href="#" class="seekto" data-time="350">5:50</a> apparently, it was meant to be foreshadowing of omega flowey.

this is the game i least expected at this very moment

madjicks's face gives me scripulous fingore vibes

gotta do a part 2 to cover the "FUN"-value dependent rooms and multiple endings! this was very engaging but we gotta see more

Id love to see what happens to the dog in the "you have too many dogs" area. I've always been curious about the area around it

I love all the early sprites and dev cubes-err, squares? Fun stuff!

<a href="#" class="seekto" data-time="203">3:23</a> yes toby came out and said that is why toriels name is toriel

<a href="#" class="seekto" data-time="400">6:40</a> Her cigarette is the wrong way. You don't light the orange end

I was waiting for this one! Love the channel!

Stuff is STILL being discovered in this game? No way!!!

<a href="#" class="seekto" data-time="476">7:56</a> That’s quite cool. <a href="#" class="seekto" data-time="488">8:08</a> Alphys was determined to go to the bathroom!

thxs for making this video! its really well put together and i bet the research from the comutniy to find this stuff must have been a task and a half! nice job on the video! keep it up!

I just randomly decided to play this game yesterday. Cool that you came out with a video about it

The game that keeps on giving! Thanks for sharing these!

Flowey goes into his own Undertale

Thank you so much! I learned a lot, and as an indie game dev and a big undertale fan, learning how the game was made has helped me make my own game, as I've been working in the same game engine as undertale.

Idk how but the past week ive been re-playing undertale and now this video comes out? Must be fate!

<a href="#" class="seekto" data-time="641">10:41</a> or what I do is set a constant offset by constantly adding or subtracting.

(You hear a passing conversation.) Error!

Congrats on 1 mil subs dude!

man you are just knocking it out of the park with the recent episodes

<a href="#" class="seekto" data-time="20">0:20</a> and toriel says the ruins is small.. Smh

I love how much this kind of stuff interests me. I’ve been doing my own smaller scaled boundary breaks in games for a few years before finding this channel, and game development has been a big goal my whole life. My only issue is I can’t for the life of me figure out a starting point to it all.

* This analysis fills you with Determination

<a href="#" class="seekto" data-time="33">0:33</a> the ruins are very small once you get to know them

Flowey: 🎵And I'm freeeee! Freeeee faaaaaaallin!'"🎵

The Underground is nothing but a treasure trove for unknown areas. <a href="#" class="seekto" data-time="685">11:25</a> And you can’t leave my shop.

<a href="#" class="seekto" data-time="311">5:11</a> I'd like to imagine that some random monster just went over there and just yelled error for the fun of it. Maybe it was Mettaton!

shoutouts to kesMadgik who does shorts on undertale and deltarune answering fan questions. a few things from this vid, i knew because of him :D

Thank you for making this video, it was fun to watch

the infinitely repeating backrounds remind me of PUs from Super Mario 64

<a href="#" class="seekto" data-time="459">7:39</a> the word immersion being used when we’re boundary breaking a 2d game is wild

Never expected this but dang it's cool

Never expected you could do camera zoom outs in a game like Undertale!

For some reason this is the first UT vid I've watched in a long time. Man miss when UT was at its height

This is probably the last thing I expected to see right now

congrats on the mill!!!

Awesome video, great work!
